The bottoms referred to are installed in tubul lar bodies which have been shaped and finished'in an apparatus disclosed in the appli- 90, cation for vpatent. upon improvements in ap- -paratus for making paper bottles, filed byv me the' 31st day,of May, 1924, said application having assigned thereto the. Serial N umber 716,968, to which application, cross reference is here made. Y

f These bodies C are disposed in a cylindrical holder 20, the supporting frame 21 whereof is shaped to fit the cylindrical portion ofvr the said body, asis' best shown in Figures 11, 12 and 13A of the drawings.'A The opposite end of the holder 20`is pierced to support a horizontally disposed tubular plunger 22. The forward end of the plunver 22 is slotted longitudinally to provide guides for' the relatively thin arms 23 and 24 of the body clamp members which are designed to hold the body C immovable in the holder A20, While the bottom forming blank 25 is being installed and shaped. This construction is shown best in Figure 10 of the drawings.

The body clamp members above referred to are constructed and arranged to form two sets. The set having the arms 24 have heads 26, the outer sides of which are curved in correspondence with the container body C. The longitudinal side edges of the heads 26 are disposed in planes parallel with the arms 23.

The heads 26 and 27 when combined and arranged interleave snugly and form a continuous ring, the sections whereof independently press upon the container body C to clamp lit against the wall of the l1older20 adjacent the exterior opening of the frame 21, as seen best in Figure 10 of the drawings.

It will be noted by reference to Figures 10 and 14, that the longitudinal side edges of the heads 27 form recesses'into which the heads 26 enter and completely fill. The side edges of the heads 27 are shaped or splayed to form a slight draft for the heads 26 as the same are withdrawn. A

In Figures 10 to 13 inclusive, there is best shown the mechanism for operating the arms 23 and 24. This consists primarily in the tube 28, rod 29 and the rocking lever 30 engaging same. The lever 30 is coupled with a manually rocked lever 31 by means of a link 32 at the rear end ofwhich is a recess 33 for engaging a pin u34a-t the lower end 0f the lever 30.

Adjustably mounted in the end walls of the recess 33 are screws 35, the arrangement of which is used for timing the engagement between the levers 30 and 31. This construction provides for certain necessary lost motion transmitted from the lever 31, which as shown best in Figure 2 of the drawings, is operated by a hand lever 36. The lever. 31 has a reduced end 37 which normally engages a recess 38 in the plunger 22. 4It is obvious that as the lever 31 is rocked on the shaft 39, the plunger 22 is reciprocated lengthwise of the holder 20. The limit of the forward movement of the plunger 22 is shown.n Figure 11', where-the forward end of the plunger 22 rests firmly against the blank 25, which forms the bottom of the container C. In Figure 13,A the extreme rearward. movements of the plunger 22 and parts assoclated therewith, are shown, the forward end thereof being withdrawn-'from contact with the bottom 25. 1

As best seen in Figure 3 of the drawings, the lever 30 is bifurcated, the extremities of the bifureated parts bearing upon the washer 41 and diskI 44. The lever 30 is rocked on its shaft 42 from the position shown` in Figure 13 of the drawings to tl1e position shown in Figure 11, in correspondence with and when actuated by the lever 31. The lever 31 is manually manipulated by the hand lever 36. The lever 36 is manipulated after the body C of the bottom has been adjusted within the apparatus. To maintain the body in position and to regulate the insertion of the bottom of the bottle and resist the thrust of the edge turning mechanism when operating thereon,

the plunger 22 and parts connected therewith are moved forward and the arms 23 and 24 are spread firmly against the body portion to clamp the same rigidly in position.

The foregoing is'accomplished as follows:

Referring to Figure 13, it will be seen thatthe plunger 22 andparts connected therewith are in what may be termed tle retracted position where the arms 23 and 24 are held within the circumference of the plunger 22, which thus permits the neck bf the bottle passing over the said plunger. The body of the bottle having been thus installed, the lever 36 is operated to rock the lever 31 on its shaft 3i). The reduced end 37 enters the recess 38 to engage the plunger 22. The continued rocking of the lever 3l advances the plunger 22 to the position shown in Figure 12 of the drawings, at which moment, the end 37 clears the recess 38 and the plunger 22 is held thereafter stationary. During this movement of the plunger 22 and the lever 31, the link 32 has moved over the pin 34 without affecting the lever 30. The advancing screw 35 now engages the pin 34 and rocksthe lever 30. It will now be noted that the further rocking of the lever 3l is ineffective to advance the plunger 22, as the curvatureof the side 50 of the recess 38 coincides with the end 37 of the lever 31. 1

It will be noted in this connection that thereafter the lever 31 prevents the plunger 22 from being forced backward.v i When the lever 30 is rocked forward as above described, it is from the position shown in Figure 13. The first part of this movement operates .through the disk 44 to advance the rod 29 until the disk 44 impinges upon the nut 40 closing the space 43. The immediate result of this is that the arms 23 are rocked outwardlyandslightly in advanceof the movement of the arms 24: This is caused primarily by the ridges 46 at vthe forward end of the rod 2 9 operating upon the-teeth of the segments- 45. Y

When the space 43 has been closed, and when the disk 44 engages the nut 40, the tube 28 is moved forward in company with the rod 29. Annular teeth on the tube 28 engage the teeth of the segment 49 of the arms 24 to rock the same arms in unison with the movement of the armsA 23. The movement of the heads 26 and 27 at the ends of the arms 24 and 23 is so plunger 22 is prevented by the lever 31 from retreating, while a similar purpose is served by the lever 30 for the rod 29 and the tube 28. 1n this way a solid wall is presented to receive the blank 25 constituting the bottoni of the bottle and to resist the pressure incident to overturning or spinning the flange 25*l and the edge of the body of the bottle.

lVhen the edges have been spun as stated, the body of the bottle is disengaged by the heads 26 and 27 of the arms 24 and 23 as the result of throwing the lever 36 backward. lfVhen this is done, the parts are moved from the position shown .in Figure 11 where it will be observed that the end 37 of the level' 31 enters the recess 38 to engage the same. As the plunger 22 is retracted, the lever 30, rod 29, and tube 28, are carried back to the position shown in Figure 12 of the drawings, in which position the end 37 of the lever 31 is leaving the recess 38, thereby permitting the plunger 22 to rest. In this position the rearmost screw has engaged the pin 34 so that the further rocking of the lever 31 rocks the lever 30 backward to the position shown in Figure 13. In this movement it will be observed that the pressure of the lever 30 being upon the disk 41, the rod 29 is pril'narily moved until the reduced end 46 thereof engages the end of the tube 28. (See Figures 12 and 13.) The movement of the reduced cnd 46 rocks the arms 23 inward, subsequently the tube 28 is drawn back by the further movement of the lever 30 with the result that the reduced end 47 of the tube engaging the teeth of the segments 49 rocks the arms 24 to their folded position simultaneously, with the similar result upon the arm 23 caused by the further movement of the reduced end 46. Thus, after the bottom has been placed and firmly secured in the bottle, the plunger 22 and the arms 23 and 24 connected therewith are folded to a dialneter which freely passes through the neck of the bottle'C. when the same is ejected by the operation of the lever 93.

At the inner end of the shaft 64 is a worm Wheel 66, the teeth whereof are engaged by a worm 67 on the driving shaft 68 of the apparatus.

It is obvious that this arrangement provides for continuously rotating the gear wheel 63, 62 and 57, but as can be seen in Figure 1 of the drawings, when the disk 53 is inactively disposed the wheel 56 is disengaged from the wheel 57. lVhen, however, the disk 53 is swung into position to enter the holder 20 and the end of the body C therein, the yoke 55 is swung as shown in Figure 5 of the drawings so that the wheel 57 is engaged by the Wheel 56, the disk 53 thereafter rotating in unison with the shaft 63 and parts associated therewith. This provides for a relatively slow rotation of the disk 53, during the period when the disk is disposed within the end of the body C.

This action is conducive to the spreading of adhesive with which the disk 53 is provided and which it collects from the raised edge 67x of the well or reservoir 68", when manually moved thereto.

As soon as the adhesive is spread inside the extended edge of the body C, the disk`53 withdrawn, the handle 69 being used for this purpose. The handle 70 thereafter serves to lower the gumming mechanism to its normal or inactive position, as shown in Figure 1, where a new supply of mucilage is administered to the edge of the disk 53. It will be understood that in positioning the disk 53, the handle 70 is employed to swing the yoke 55 around the shaft 64, the wheels 62 and 63 permitting this movement. `Preliminary to placing the disk 53 within the body of the container C, the yoke 59 is moved upon its pivots to engage the wheels 56 and 57 as shown best in Fig. 5 of the drawings. Sufficient fiexibility is allowed in the mechanism to permit the forward movement of the shaft 61 and the yokes 59 and 55 connected therewith to permit the movement of the disk 53 into, and the withdrawal from the body of the container C.

The necessary adhesive having been applied the next step in the operation is to place the disk 25 and to seat it properly within the extended edge of the body C. In Figure 6 of the drawings, the disk is shown in its flat position disposed in front of or covering the open end of the body C. In Figure 4 of the drawings in broken lines, the disk is shown as descending to enter the splayed or flanged edge 71 which guides the disk 25 into the receptacle slot 72 formed in the housing.

The means for reciprocating the plunger 51 in the housing 73 consists primarily of the racked plunger 74` the teeth of which are engaged by a small pinion 75. The pinion 75 is mounted on a shaft 76 at the outer end whereof is provided a lever 77, best seen in Figure 1 of the drawings.

The lever 77 is used for rocking the shaft 76 and the pinion 75 thereon, with the result that the plunger 74 is retracted to a position outside of the slot 72, or advanced to a position inside of the slot 72. The diameter of the interior of the housing 73 is such as to permit the edge of the disk 25 to fold over the cylindrical edge of the plunger 51.

In the operation of the plunger 51 and parts associated therewith, the disk 25 having been deposited in the slot 72 while the plunger 51 is in its retracted position, the operator rocks the shaft 76 and wheel 75 by means of the lever 77, with the result that the racked plunger 74. the phmger 51, and the disk 25 are carried forward to the position shown in Figure 4 of the drawings, the circular margin 'of the disk 25 being laid back over the plunger 51, as shown in the said Figure 4. Having deposited the disk 25 in the position shown in llO Figure 4, the plunger 51 is retracted to the full of its movement to a position outside of the slot 72, when a succeeding disk 25 may be inserted in said slot.

As each bottom or disk 25 is placed in position, the housing 73 and parts associated therewith, are lifted to a position clearing the end of the holder 20. To this end the housing 7 3 is provided with bracket arms 78 which are pivotally mounted on a shaft 79.

The bracket arms 78 have shoulders 80 which rest upon stop pins 81 formed on the far side of the shaft 79 in the frame 21, as seen best in Figure 2 of the drawings. In this position. the housing` 72 and parts associated therewith are thrown out of balance on the far side of the apparatus, leaving the space in front of the apparatus clear for the operation of the spinning or curling shaper 52.

The shaper 52 is mounted on a shaft 82 with the transmission gear wheel 83. The wheel 83 is driven from the shaft 84 by means of the train of gear wheels 85, 86 and 87, which are supported in a frame 88, having a handhold 89. The shaft 84 is driven from the shaft (38 through the gear Wheel 90. The frame 88 is rotatively mounted on the shaft 84 while the gear wheel 85 is slidably keyed thereto. This arrangement provides for the movement lengthwise of the shaft 84 of the frame 88 and gear train associated therewith. Normally, the frame 88 and parts associated therewith are held outward from the frame 21 by the spring 91. as best seen in Figure 3 of the drawings. The limit of the outward movement of the frame 88 is controlled by the disk 92.

When desiring to curl the end of the body C andthe flange 25", the operator using the handle 89 swin gs the frame 88 around the shaft 84 to oppose the shaper 52 over the exposed end of the body C. At all times, the shaper 52 is rotating. lVhen thereafter it is pressed upon the said end of the body C and said flange, the said end and fiange are overturned and curled to con form to the shape of the shaper 52 which is grooved, as seen best in Figure 11 of the drawings. The edge following the form of the groove is overturned or curled. In practice the curled edge of the end of the body C and of the flange 25a rests against the bottom forming portion of the disk 25, thereby constructing for the container C, a reinforced edge portion for setting the container upon the reinforced portion referred to, being four-ply in thickness.

lVith the completion of the operation of the shaper 52. the operation of the present apparatus is completed. with the exception of the delivery of the container from the holder 20. This is accomplished by the stripping lever.

As bestl shown in Figures 11 to 13 inclusive, the lever 93 has a pivot shaft 94 and spreading yoke arms 95. The extremities of the arms 95 bear upon the end of the container body C when the same is placed in the holder 20, as shown in the figures of the drawings referred to. When now, the shaper 52 as been removed from the path of the body C, the stripping lever 93 is manually rocked backward toward the rear of the ap aratus with the result that the ends of the yole arms 95 engage and press upon the pouring end of the body C, thereby forcing the body C outward from the holder 20 to a position where it is manually engaged and withdrawn from the said holder.

1t will now be found that the container body is completely finished, having a liquid-tight bottom and a reinforced supporting edge therefor, which is the result. of the combined operations of an apparatus disclosed in application for patent bearing Serial Number 716,968 filed 31st day of May, 1924, and the.
